Abstract

The invention relates to a 8x8 cross-country-vehicle independent suspension frame double-steering device with double steering gears, and solves the problem in the prior art that ideal coordination on steering angles of a first front axle and a second front axle cannot be achieved. The double steering device comprises a first angle steering gear, a steering transmission shaft, a second angle steering gear, a first axle steering transmission shaft, a first axle vertical arm, a first axle steering gear, a first axle steering straight pull rod, a first axle steering trapezoidal mechanism I, a second axle steering transmission shaft, a second axle vertical arm, a second axle steering pull rod, a second axle steering rocker arm, a second axle steering straight pull rod, a second axle steering gear and a second axle steering trapezoidal mechanism II; the first angle steering gear is connected with the second angle steering gear by the steering transmission shaft; the second angle steering gear is connected with the first axle steering gear by the first axle steering transmission shaft, and is connected with the second axle steering gear by the second axle steering transmission shaft; the first axle steering gear is connected with the first axle steering trapezoidal mechanism I; and the second axle steering gear is connected with the second axle steering trapezoidal mechanism II. By adopting the double-steering device, the error for the steering angles of the first front axle and the second front axle is small.

Description

technical field [0001] The invention relates to a dual steering system, in particular to a dual steering device of an 8X8 off-road vehicle independent suspension dual steering gear. Background technique [0002] At present, the traditional 8x8 off-road vehicle with independent suspension and double front axle steering, its dual steering power system is mainly a steering gear as the main power transmission force, and then matched with a booster cylinder as an auxiliary force transmission to make the steering control light. The design of the matching structure is complicated, and the calculation of the transmission mechanism is complicated. The steering angle coordination of the first and second front axles is not ideal. The actual steering angle is compared with the theoretical Ackerman angle. The error is large, and the stability of the steering booster cylinder is not very good. Steering controllability is not ideal. If the steering system design is unreasonable, it will ca...
